Figure 3 is a plan, partly in section, illustrating the saw support,

Figure 4 is a fragmentary sectional view illustrating the setting tool and the anvil,

Figure 5 is a detail illustrating the handle for operating the shifting element for the saw support.

Referring to the drawings in detail, a saw set in accordance with this invention comprises an inverted U-shaped head 1, having projecting from the lower terminus of one of the legs or arms thereof a laterally disposed support 1*, provided with openings 17, through which are adapted to extend hold-fast devices, not shown, for fixedlysecuring the head 1, to a suitable support.

Depending from the extension 1 is a vertically disposed guide bar 2, formed at its upper end with a reduced extension 2, which is peripherally threaded. The bar 2, is secured to the extension 1, by a nut 14, having threaded engagement with the reduced threaded end 2, of the bar 2.

A vertically adjustable supporting element is provided for the saw, for holding the latter during the setting operation and the said element consists of a cylindrical sleeve 3, slidably and adjustably mounted on the guide bar 2, and which is maintainedin its adjusted position, by a clamping screw 5, the latter being carried, by the sleeve 3, and capable of engaging with the bar 2, for maintaining the sleeve 3, in its adjusted position. Projecting laterally from the sleeve 3, as well as being formed integral therewith, is an arm 5, provided with a vertically disposed opening having the wall thereof threaded. The arm 5, terinmates in a rectangular plate 7 which has projecting outwardly therefrom a cylindrical extension 6, carrying a cone-shaped member on which a saw is rotatably supported, and which is fixedly secured against the plate 7, by a collar 9, mounted on the extension 6, and detachably secured in position by a lock screw 10. Adjustably mounted at each end of the plate 7, is a threaded holding member, and each of said members 1.1, is secured in its adjusted position by the nuts 12, these latter abut against the forward and rear face of the plate 7. The holding members 11, are arranged at each side of the support 8. The saw tofbe operated on, is mounted on the cone-shaped support 8, and theme-miners 11, are adjusted toss-am a retainin action with respect to the saw, when the Ta thereby preventing the lateral shifting of the saw dur'ing the setting operation. The support 8', extends through the central opening in the saw and as said support '8, is

conoidal incontour,-provis1on re -made for" the mounting thereof in openings ofdifi'er ent slzes, at the center of the saws, and "furthermore the shape of said support 8, with,

respect to the holding members 11, provides for awedge actionto take place so that the saw is sccurelyheld imposition. The openibe rnounted on the extended portion 4a, of

theshait 4,.Yis a crank 16, having a notched lower end 16 for the purpose,ofstraddling the lug-I15. The crank 16, is employed for rotating the shaft 4, to vertically adjust the saw supporting element.

Secured to the inner face of one of the arms or legs of the head 1,'that is theouter arm or leg, by the hold-fast devices 22, is a casing or housing-18, for the setting tool 19. vArranged within the housing 18, and

inc'losing the too1f19, is a coiled spring 20,

employed for returning the tool'19, to normal position. The tool 19, permanently projects fromthe-housing' 18. "That leg or .arlnfof the head 1, to j which the housing 18,

is secured, is formed with anopeninghavmg the wall thereof threaded, and threadably engaging with the wall-of said opening,

is an operating means for the tool 15), and which conslsts of a threaded arm formed witha reducedlnn'er end engageable'with the tool 19, for forcing the latter inwardly to set atoo'th, whenthe arm 23, is revolved.

v Secured to the outer lendof the arm 23,

and maintained thereon through themedium of a nut 24, isJan operating lever 25,:tor the arm 123. For limiting the movement of the lever 25," that arm or legot the head with which the arm 23, engages, adjustably securedtheretm by the detachable holdfast devices 27', a slotted, stop member '26, the

latter being. arranged in the path of the arm 25 Secured .toth'at'leg orarm of the head 1, opposite that log or arm carrying the lions ling 13, is an anvil 28, positioned to cooperate with thejtool 19, formed on the inner end of "a short bar having threaded engagement withthe armor leg of the head, and secured in pos ony 311L117 29. The feed ani mjor device. for the saw, com a eurved bdlt 3fig' securecl to "that aim for? leg tter is mounted on a support 8,]

of the head 1, which carries the anvil, 23,

"and the said curved bolt 39 is maintained in position by a nut 4-0, and carries on its outer end a feed lever, mounted for" rocking movement on said outer end of the bolt 39, and maintained in position by a nut 41.

The feedileverisformed of two sections 3 1, v

35, the latter telescoping on the former and is provided at its lower end with a laterally disposed finger 38, adapted to be positioned in the gullets of the saw and engage the vertical edge of the teeth for intermittently rotating the saw to positiona? tooth to be acted on by the tool 19. A .pin 37,'is provided in the section 34:, to limit the downward movement of the section'35 ofth'e feed lever- The section 35, of the feed lever provided at"its'upper end with a handle '36, and interposed between the upper end. or the section 3 1, and the top of the handle 36, is a coiled spring 36 for normally maintaining the section35, extended above thc sco tion 34 A pin 35 is provided on the upper end of the sect on 34, and extends in slots 35", formed in the upper'portion of thesection 35, to prevent the latter rotating with respect to the section 3%.

The feedingmovementof the feeding lever is controlled so'as to provide for differentspaced or sizes of saw teeth, by a pair oi adjustable stop elements d3, which are threaded, and carry securing nuts 44. The stop elements 13, are mounted in a slotted bracket 42, through which extends the section 34, or the feed lever. The bracket 12 is angle shaped and is secured to that arm or leg of the head 1, which is provided with the housing 18, nut 46. V c

To prevent the body of the saw from be ing sprung, when pressure is applied to the by a bolt 45, provided with a teeth thereof, during the setting operation, 3 each of the arms or legs or the head 1, 1s

provided with an adjustable abutment member and each of these abutment members is in the form of a, threaded bolt having threaded engagement with an arm or leg ot' the head 1. The abutment members extend in opposite directionsivith respect to each other and one is arranged above the other.
